NAME
SSL_library_init, OpenSSL_add_ssl_algorithms, SSLeay_add_ssl_algorithms
- initialize SSL library by registering algorithms
SYNOPSIS
#include <openssl/ssl.h>
int SSL_library_init(void);
#define OpenSSL_add_ssl_algorithms() SSL_library_init()
#define SSLeay_add_ssl_algorithms() SSL_library_init()
DESCRIPTION
SSL_library_init() registers the available ciphers and digests.
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms
for SSL_library_init().
NOTES
SSL_library_init() must be called before any other action takes place.
WARNING
SSL_library_init() only registers ciphers. Another important initialization
is the seeding of the PRNG (Pseudo Random Number Generator), which has to
be performed separately.
EXAMPLES
A typical TLS/SSL application will start with the library initialization,
will provide readable error messages and will seed the PRNG.
SSL_load_error_strings(); /* readable error messages */
SSL_library_init(); /* initialize library */
actions_to_seed_PRNG();
RETURN VALUES
SSL_library_init() always returns ``1'', so it is safe to discard the return
value.
